Abstract

The invention provides a shifting device and a vehicle, belonging to the technical field of automobiles. The device includes a ring gear, a planet carrier, a planetary gear, a first shifting part, a second shifting part and a first elastic element. One side of the ring gear is provided with a first disc, the first end of the second fixed part included in the planet carrier is provided with a second disc, the first end of the first shifting part is provided with a third disc, and the second shifter is provided with a second disc. The first end of the shifting part is movably connected with the second end of the first shifting part, the second end of the second shifting part is provided with a hydraulic element, and the first elastic element is located between the shoulder of the first shifting part and the second shifting part. Between the end faces of the first end of the blocking member. The entire shifting process does not require the use of independently operated components such as oil pumps and air compressors, so that the entire device occupies a small space. The entire shifting process does not need to go through multi-stage conversion to achieve shifting operations, and the device responds better. .

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a shifting device and a vehicle. Background technique [0002] The powertrain of a new energy vehicle mainly includes a motor and a reducer. The reducer mainly adopts a gearless form, a single-speed form and a two-speed form. Among them, since the two-speed reducer needs to meet the driving conditions of different working conditions, it is necessary to Add a shifter after the reducer. [0003] At present, shifting devices mainly include electronically controlled electrohydraulic, electropneumatic and electronically controlled electric. Among them, the electronically controlled electro-hydraulic shifting device and the electropneumatic shifting device are controlled by the electronic control unit to complete the shifting work of the reducer. [0004] However, the solenoid valve included in the electro-hydraulic shifting device must be used in conjunction with the oil pump an...
